Ocular Biometry in Patients with Primary Open Angle Glaucoma (POAG)

Vijaya Pai *,Rohith Simha Thota

Purpose: To compare ocular biometry in patients with POAG (Primary open angle glaucoma) and age-matched controls.

Methodology: Cross sectional epidemiological study at a tertiary care center between October 2014 to August 2016. Patients with POAG formed the study group. Control group included those patients who did not have glaucoma and who were posted for the cataract surgery. Axial length (AL) was measured using Ultrasound A scan (TOPCON KR8900) by immersion technique and keratometry 'K' value measured using auto refractokeratometry [ALCON orbscan]. Statistical analysis was done using student 't' test.

Results: 212 eyes of 140 patients were included in the study. There were 106 eyes in each group. Age of the patients varied from 50-90 years in the study group and 48-79 years in the control group. AL in POAG (23.88 mm ± 0.19) was significantly higher (p<0.0000) than age-matched controls (22.0 mm ± 0.10). K value in POAG (44.29 D ± 0.19) was significantly lower (p<0.0001) than age-matched controls (45.38 D ± 0.14).

Conclusion: Patients with POAG seem to have longer AL and flatter corneas when compared to age-matched controls.
